ST. LOUIS, Nov. 5, 2025 /PRNewswire/ -- Ameren Corporation (NYSE: AEE) today announced third quarter 2025 net income attributable to common shareholders in accordance with generally accepted accounting principles (GAAP) of $640 million, or $2.35 per diluted share, compared to third quarter 2024 GAAP net income of $456 million, or $1.70 per diluted share. Excluding a third quarter 2025 tax benefit and certain 2024 charges described below, Ameren recorded third quarter 2025 adjusted (non-GAAP) net income attributable to common shareholders of $592 million, or $2.17 per diluted share, compared to third quarter 2024 adjusted (non-GAAP) net income attributable to common shareholders of $500 million, or $1.87 per diluted share.

Third quarter 2025 adjusted earnings reflected increased infrastructure investments, new Ameren Missouri electric service rates that became effective June 1, 2025, and higher Ameren Missouri retail sales, primarily driven by warmer July weather in the current period. These positive factors were partially offset by higher interest expense at Ameren Parent and Ameren Missouri, as well as higher energy center and tree trimming expenditures that drove higher operations and maintenance expenses at Ameren Missouri. Finally, the earnings per diluted share comparison reflected higher weighted-average basic common shares outstanding in the third quarter 2025.

"We are executing across all elements of our strategy, including hardening the grid, expanding our balanced generation portfolio and supporting economic development," said Martin J. Lyons, Jr., chairman, president and chief executive officer of Ameren Corporation. "These efforts reflect our commitment to investing in a reliable and resilient energy future that provides value for our customers and communities." 

Ameren recorded GAAP net income attributable to common shareholders for the nine months ended September 30, 2025, of $1,204 million, or $4.43 per diluted share, compared to GAAP net income attributable to common shareholders for the nine months ended September 30, 2024, of $975 million, or $3.65 per diluted share. Excluding a third quarter 2025 tax benefit and certain 2024 charges described below, Ameren recorded 2025 adjusted net income for the nine months ended September 30, 2025, of $1,156 million, or $4.25 per diluted share and 2024 adjusted net income for the nine months ended September 30, 2024, of $1,030 million, or $3.86 per diluted share.

The increase in year-over-year nine month adjusted earnings reflected increased infrastructure investments, new Ameren Missouri electric service rates and higher Ameren Missouri electric retail sales, primarily driven by colder winter and warmer July weather in the current period. These positive factors were partially offset by higher interest expense at Ameren Missouri and Ameren Parent and higher operations and maintenance expenses at Ameren Missouri.

As reflected in the table below, the following items were excluded from adjusted earnings for the three-month and nine-month periods ended September 30, 2025, and 2024, respectively.

Earnings Guidance

Ameren now expects 2025 GAAP EPS to be in the range of $5.08 to $5.28 and 2025 adjusted EPS to be in the range of $4.90 to $5.10, both of which reflect an increase from the original 2025 EPS guidance range of $4.85 to $5.05. The adjusted EPS range excludes the third quarter 2025 tax benefit described above.

Ameren expects 2026 diluted EPS to be in the range of $5.25 to $5.45.

Earnings guidance for 2025 assumes normal temperatures for the last three months of the year, and earnings guidance for 2026 assumes normal temperatures for the full year. Earnings guidance for 2025 and 2026 is subject to the effects of, among other things: regulatory, judicial and legislative actions; energy center and energy transmission and distribution operations; energy, economic, capital and credit market conditions; customer usage; severe storms; market returns on company-owned life insurance investments; unusual or otherwise unexpected gains or losses; and other risks and uncertainties outlined, or referred to, in the Forward-looking Statements section of this press release.

Ameren Missouri Segment Results

Ameren Missouri third quarter 2025 earnings were $518 million, compared to third quarter 2024 GAAP and adjusted earnings of $381 million and $415 million, respectively. Adjusted earnings in 2024 excluded the above-described mitigation charges related to an agreement in principle to settle the Rush Island Energy Center New Source Review and Clean Air Act proceeding. On an adjusted basis, the year-over-year increase reflected earnings on increased infrastructure investments, new electric service rates that became effective June 1, 2025 and higher electric retail sales, primarily driven by warmer July weather in the current period. These positive factors were partially offset by higher interest expense and higher operations and maintenance expenses, the latter driven primarily by higher energy center and tree trimming expenditures.

Ameren Transmission Segment Results

Ameren Transmission third quarter 2025 GAAP and adjusted earnings were $151 million and $103 million, respectively, compared to third quarter 2024 GAAP and adjusted earnings of $90 million and $100 million, respectively. Adjusted earnings in 2025 excluded the above-described tax benefit related to a Federal Energy Regulatory Commission (FERC) order on net operating loss carryforwards. Adjusted earnings in 2024 excluded the above-described charges for customer refunds from a FERC order on the Midcontinent Independent System Operator's (MISO) allowed base return on equity.

Ameren Illinois Electric Distribution third quarter 2025 earnings were $57 million, compared to third quarter 2024 earnings of $56 million.

Ameren Parent Results (includes items not reported in a business segment)

Use of Non-GAAP Financial Measures

In this release, Ameren has presented adjusted earnings and adjusted earnings per share, which are non-GAAP measures and may not be comparable to those of other companies. A reconciliation of GAAP to non-GAAP information is included in this release. Generally, adjusted earnings or losses include earnings or losses attributable to Ameren common shareholders and exclude income or loss from significant discrete items that management does not consider representative of ongoing earnings, such as the cumulative impact of the first and third quarter 2024 charges for additional mitigation relief related to an agreement in principle to settle the New Source Review (NSR) and Clean Air Act proceeding, a third quarter 2024 charge for customer refunds related to the FERC's October 2024 order on MISO's allowed base return on equity, and a third quarter 2025 tax benefit related to a FERC order on net operating loss carryforwards. Ameren uses adjusted earnings internally for financial planning and for analysis of performance. Ameren also uses adjusted earnings as the primary performance measurement when communicating with analysts and investors regarding our earnings results and outlook, as the company believes that adjusted earnings allow the company to more accurately compare its ongoing performance across periods. In providing adjusted earnings guidance, there could be differences between adjusted earnings and earnings prepared in accordance with GAAP as a result of our treatment of certain items, such as those described above.
